Use the
undo authentication-mode
command to cancel the authentication attribute of this area.
By default, an area does not support authentication attribute.
All the routers in one area must use the same authentication mode (no authentication, simple text
authentication, or MD5 cipher text authentication). If the mode of supporting authentication is
configured, all routers on the same segment must use the same authentication key.
Use the
ospf authentication-mode simple
command to configure a simple text authentication key.
Use the
ospf authentication-mode md5
command to configure the MD5 cipher text authentication
key if the area is configured to support MD5 cipher text authentication mode.
After you configure one OSPF area to support the authentication attribute, you need to use the
ospf
authentication-mode
command to set the authentication mode on interfaces. When configuring virtual
link authentication, you can use the
authentication-mode
command to specify the authentication
mode as MD5 cipher text or simple text for the backbone area.
